Kim, Hae Min, Yang, Christopher C., Abels, Eileen G. and Zhang, Mi (2012): A qualitative analysis of information dissemination through Twitter in a digital library. In: JCDL12 Proceedings of the 2012 Joint International Conference on Digital Libraries 2012. pp. 339-340.

This study examines the use of Twitter in a digital library, the Internet Public Library (ipl2), to understand the content and dissemination patterns of Twitter messages posted by the ipl2. We conducted a content analysis on ipl2's messages on Twitter to develop a categorization of the type of tweets, and examined retweets and the active users who retweeted ipl2 tweets. We present our analysis of four areas related to the tweets: motivation, content, audience, and sources. Active users are categorized into eight groups. The research findings contribute to a further understanding of the actual use of Twitter in a digital library.

Yang, Christopher C., Winston, Flaura, Zarro, Michael A. and Kassam-Adams, Nancy (2011): A study of user queries leading to a health information website: AfterTheInjury.org. In: Proceedings of the 2011 iConference 2011. pp. 267-272.

AfterTheInjury.org is a direct to health consumer, empirically-grounded Web-based program that is hosted by an academic medical center. Launched in 2009, it includes information and psycho-education interventional content for parents of injured children. This study analyzes search engine queries that led users to the website in order to better understand the informational needs of users of such a website. Query data were collected for the 2009 calendar year via Google Analytics, a widely used free website statistics and traffic analysis tool. Specific analyses included query length and the presence of question words. Results were compared between external and internal queries. Results from this study were put in the context of existing literature regarding user search behavior. Analyses demonstrated that external search engines were an important source of traffic to AfterTheInjury.org with 1 in 5 visits driven from the most popular search engines, Google, Yahoo and Bing. Queries were longer than typical queries (AfterTheInjury query averaged 6.27 terms; typical medical query, 2.3-2.4 terms). Nearly 1/4 of queries leading to AfterTheInjury.org took the form of questions: 22.7% of external searches were questions with 10.7% of external

Liu, Nan and Yang, Christopher C. (2007): A link classification based approach to website topic hierarchy generation. In: Proceedings of the 2007 International Conference on the World Wide Web 2007. pp. 1127-1128.

Hierarchical models are commonly used to organize a Website's content. A Website's content structure can be represented by a topic hierarchy, a directed tree rooted at a Website's homepage in which the vertices and edges correspond to Web pages and hyperlinks. In this work, we propose a new method for constructing the topic hierarchy of a Website. We model the Website's link structure using weighted directed graph, in which the edge weights are computed using a classifier that predicts if an edge connects a pair of nodes representing a topic and a sub-topic. We then pose the problem of building the topic hierarchy as finding the shortest-path tree and directed minimum spanning tree in the weighted graph. We've done extensive experiments using real Websites and obtained very promising results.

In this work, we study similarity measures for text-centric XML documents based on an extended vector space model, which considers both document content and structure. Experimental results based on a benchmark showed superior performance of the proposed measure over the baseline which ignores structural knowledge of XML documents.

Shi, Xiaodong and Yang, Christopher C. (2006): Mining related queries from search engine query logs. In: Proceedings of the 2006 International Conference on the World Wide Web 2006. pp. 943-944.

In this work we propose a method that retrieves a list of related queries given an initial input query. The related queries are based on the query log of previously issued queries by human users, which can be discovered using our improved association rule mining model. Users can use the suggested related queries to tune or redirect the search process. Our method not only discovers the related queries, but also ranks them according to the degree of their relatedness. Unlike many other rival techniques, it exploits only limited query log information and performs relatively better on queries in all frequency divisions.

Yang, Christopher C. and Shi, Xiaodong (2006): Discovering event evolution graphs from newswires. In: Proceedings of the 2006 International Conference on the World Wide Web 2006. pp. 945-946.

In this paper, we propose an approach to automatically mine event evolution graphs from newswires on the Web. Event evolution graph is a directed graph in which the vertices and edges denote news events and the evolutions between events respectively, in a news affair. Our model utilizes the content similarity between events and incorporates temporal proximity and document distributional proximity as decaying functions. Our approach is effective in presenting the inside developments of news affairs along the timeline, which can facilitate users' information browsing tasks.

Hyperlink analysis has been widely investigated to support the retrieval of Web documents in Internet search engines. It has been proven that the hyperlink analysis significantly improves the relevance of the search results and these techniques have been adopted in many commercial search engines, e.g. Google. However, hyperlink analysis is mostly utilized in the ranking mechanism of Web pages only but not including other multimedia objects, such as images and video. In this project, we propose a modified Multimedia PageRank algorithm to support the searching of multimedia objects in the Web.

The Chinese text segmentation is important for the indexing of Chinese documents, which has significant impact on the performance of Chinese information retrieval. The statistical approach overcomes the limitations of the dictionary based approach. The statistical approach is developed by utilizing the statistical information about the association of adjacent characters in Chinese text collected from the Chinese corpus Both known words and unknown words can be segmented by the statistical approach. However, errors may occur due to the limitation of the corpus. In this work, we have conducted the error analysis of two Chinese text segmentation techniques using statistical approach, namely, boundary detection and heuristic method Such error analysis is useful for the future development of the automatic text segmentation of Chinese text or other text in oriental languages. It is also helpful to understand the impact of these errors on the information retrieval system in digital libraries.

In this paper, we introduce the fractal summarization model based on the fractal theory. In fractal summarization, the important information is captured from the source text by exploring the hierarchical structure and salient features of the document. A condensed version of the document that is informatively close to the original is produced iteratively using the contractive transformation in the fractal theory. User evaluation has shown that fractal summarization outperforms traditional summarization.

Wireless access with mobile (or handheld) devices is a promising addition to the WWW and traditional electronic business. Mobile devices provide convenience and portable access to the huge information space on the Internet without requiring users to be stationary with network connection. However, the limited screen size, narrow network bandwidth, small memory capacity and low computing power are the shortcomings of handheld devices. Loading and visualizing large documents on handheld devices become impossible. The limited resolution restricts the amount of information to be displayed. The download time is intolerably long. In this paper, we introduce the fractal summarization model for document summarization on handheld devices. Fractal summarization is developed based on the fractal theory. It generates a brief skeleton of summary at the first stage, and the details of the summary on different levels of the document are generated on demands of users. Such interactive summarization reduces the computation load in comparing with the generation of the entire summary in one batch by the traditional automatic summarization, which is ideal for wireless access. Three-tier architecture with the middle-tier conducting the major computation is also discussed. Visualization of summary on handheld devices is also investigated.
